Keytool facebook app for android not working on device

I've been trying for 4 hours to discover how to use the keytool stuff. My app works so well in the emulator. I've tried almost all of tutorials and tips in StackOverflow, G开发者_如何学Coogle and others. Now, I'm really frustrated, because this is my first time trying to use facebook stuff on the device.

Please, does anyone have a tutorial for beginners to help me solve this?

I'm using Windows 7 and Eclipse.

You need to create custom key-store, if you want to work your apps in device.

Visit two link page. link1 link2 how to use Facebook sdk.. use custom keystore instead of debug keystore. I just hope that this time your apps will work.
